Adding items to Menu from code behind

[maephisto]

hi!

I'm trying to add some items to a button's menu like this :

<ext:Button ID="btnSelectCat" runat="server" Icon="TableColumn" Text="[Select Column]" FieldLabel="Category">
                                                                                <Menu>
                                                                                    <ext:Menu ID="SelectCategoriesCmb" runat="server" >
                                                                                        <Defaults>
                                                                                            <ext:Parameter Name="HideOnClick" Value="false" Mode="Raw" />
                                                                                        </Defaults>
                                                                                        <Items>
                                                                                            <ext:CheckMenuItem ID="CatHeader" runat="server" Text="Header" CheckHandler="headerChecked" />
                                                                                            <ext:MenuSeparator />
                                                                                            
                                                                                        </Items>                    
                                                                                    </ext:Menu>
                                                                                </Menu>
                                                                            </ext:Button>

and in the code behind :

CheckMenuItem.Config cfg = new CheckMenuItem.Config();
                        cfg.Text = col.ColumnName;
                        cfg.CheckHandler = "colChecked";
                        SelectCategoriesCmb.Items.Add(new CheckMenuItem(cfg));

This happens in an ajax event, but after that i see no change in the menu - no items added.
What else should i do ?
Thanks!
